Digital Vibration Calibrator, vibration measuring instruments,calibrate accelerometer, velocity
Application for Vibration Calibrator:
1.Can be used to calibrate vibration accelerometer, velocity and proximity transducer and also a
vibration measuring instruments. Standard sine signals at frequency 10, 20, 40, 80, 160, 320,
640 and 1280 Hz
2.Can be generated from the calibrator the amplitude of the acceleration, velocity and
displacement
3.Can be defined through potentiometers and shown on digital displays. Either horizontal or
vertical vibration can be generated.
4.VMC-5000 vibration calibrator combines sine signal generator, power amplifier,
standard transducer and a shaker in one and features a small volume, high accuracy
and easy operation. It can be used either in laboratory or on site.

Maximum vibration amplitude and maximum load:
Because of the vibrostand used in VMC-5000 Vibration Calibrator is rather small, during the
calibration of transducers of different weight under different frequencies the output amplitude of
the calibrators are also different. Maximum vibration amplitude and maximum load are related to
the maximum acceleration. Maximum velocity and maximum displacement output generated from
the calibrator under a certain frequency and with a certain weight of the transducer to be
calibrated.
The specific figures can be seen in the following table.

Note: With higher frequency the value of the displacement of vibration is very small so there
will be no vibration signal output from the calibrator.
